(A) Latency to reach the arm, (B) latency to reach the hole, and (C) percentage of time spent at the hole for mice being confronted with solely positive (optimistically-trained mice, n = 7) or solely negative (pessimistically-trained mice, n = 7) experience across the three days of training. Data are averaged per treatment group and day and are presented as means ±SEM. Day 1: 5 trials, day 2: 6 trials, day 3: 2 trials. See results section for details of statistical analysis.
